------------------------------------------
Summary: Ozone: MiniOzoneCluster uses 400+ threads
Key: HDFS-12163
URL: https://issues.apache.org/jira/browse/HDFS-12163
Project: Hadoop HDFS
Issue Type: Bug
Components: ozone, test
Reporter: Tsz Wo Nicholas Sze
Checked the number of active threads used in MiniOzoneCluster with various
settings:
- Local handlers
- Distributed handlers
- Ratis-Netty
- Ratis-gRPC
The results are similar for all the settings. It uses 400+ threads.
Moreover, there is a thread leak -- a number of the threads do not shutdown
after the test is finished. Therefore, when tests run consecutively, the later
tests use more threads.
Will post the details in comments.
